摘要： An apparatus for inserting and removing both control rods and fuel elements from holes in a nuclear reactor has a vertically and horizontally displaceable support pivotally carrying a head which has a pair of grabs on its opposite ends, one of which is formed as a pair of pawls adapted to lock on the collar at the end of a fuel element and lift this element and the other of which is adapted to engage within a group of control rods to unlock them from their respective fuel elements and grip them so that they can be lifted from the respective fuel element. To this end the housing having the two grabs is provided with a small pneumatic cylinder whose piston is displaceable against spring force in one direction and is connected to both of the grabs so that on displacement in this direction it opens both of the grabs, the spring therefore serving to hold these grabs closed should pneumatic pressure fail. The grab head is pivotal on the support about a horizontal axis on pins serving as the pivot for this head and provided with pinions meshing with racks that can be displaced up and down so as to rotate the head through 180.degree., thereby aligning either of the grabs with a respective object. In addition locking means is provided so as to hold this head in either of these positions, thereby preventing it from tilting and dropping a group of control rods or a fuel element.

摘要： A charging device, especially for supplying aluminum in the form of wire to a steel melt for quieting the melt, in which a frame positioned adjacent the melt vessel has an inclined wall on the side facing the melt and a boom slidable along the inclined wall contains feed rollers for feeding a wire through a feed tube toward the melt. The wire is derived from a reel supported in the frame with the reel being driven in payout direction. The wire is cut off at the lower end of the feed tube and is dropped into the melt together with a combustible guide sleeve which is releasably clamped to the feed tube.

摘要： A device for changing the location of fuel elements and control rods in a core reactor with a guiding mast which is mounted on a movable working platform for rotation about a vertical axis and which is provided with a gripping body for grasping the fuel elements and control rods, said gripping body being suspended on a lifting mechanism and being displaceable in vertical direction within the guiding mast while being prevented from rotating relative to the guiding mast. The device furthermore comprises winding means for storing supply lines which are introduced at the top into the guiding mast and the gripper body.The device also includes power operated means for actuating the lifting mechanism. The winding means and lifting mechanism rotate with the mast and are so arranged in the mast that any water dripping therefrom runs down the inside of the mast. Supply conduits leading to the mast are connected thereby by slack loops which permit 360.degree. of rotation of the mast.

摘要： A device for gripping bundles of control bars or rods for extracting the control bars from and introducing the control bars into fuel cells of nuclear reactors in which the control bars are in bundles connected by a spider-like head at the top and the gripping device includes a plate with a perforation through which the head can pass. When the head is released from the fuel cell and lifted upwardly through the plate, the plate provides lateral guidance for the control rods thereby facilitating replacement of the control rods into a fuel cell. The gripping device includes a reciprocable gripper body in a gripper tool detachably connectable thereto and to said head and guided on said plate by guide members projecting from the plate.
